Most days after school, I love walking in the forest with my dog Nick. It’s 11 (peace), especially around sunset. Nick has a fun time smelling the leaves and running after rabbits. When Nick runs ahead, I hear him barking excitedly. I sometimes call him back, worried that he might have someone 12 (scare). The truth, though, is 13 could be guessed — there’s never anyone else here. Just me, Nick, and the quiet forest.
